1. A terminal device that communicates with a base station device, the terminal device comprising:
a receiver for receiving sounding reference signal (SRS) setting information and setting information for signals, the signals having a spatial correlation that is set to at least one SRS; and
a transmitter for transmitting the at least one SRS, wherein:
the SRS setting information includes information indicating the spatial correlation with the at least one SRS;
the transmitter, when transmitting the at least one SRS, sets a first spatial domain transmission filter and a second spatial domain transmission filter;
a first spatial domain reception filter and the first spatial domain transmission filter are set with beam correspondence;
a second spatial domain reception filter and the second spatial domain transmission filter are set with beam correspondence;
the setting information for the signals having the spatial correlation set to the at least one SRS includes information identifying the first spatial domain reception filter and the second spatial domain reception filter; and
the transmitter transmits the at least one SRS using at least one of the first spatial domain transmission filter and the second spatial domain transmission filter based on the information indicating the spatial correlation with the at least one SRS and the signals having the spatial correlation set to the at least one SRS.
